TANK FOR WATER-CLOSETS.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed May 23, 1908. Serial No. 434,618.

To all whom it may concern:

Be it known that I, GEORGE H. BAILEY, a resident of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Tanks for Tater-Closets, of which the following isa specification.

This invention relates to flushing tanks for water closets and the like.

The object is to provide a tank constructed of sheet metal and enameled.

The invention comprises a tank constructed and finished in the mannerhereinafter described.

In the accompanying drawings Figure 1 is a perspective view of myimproved tank; Fig. 2 is in part an elevation and in part a verticallongitudinal section through said tank; Fig. 3 is a transversesectionthrough the same showing one. form of top and bot# tcm finish; Fig. 4 isa vertical sectional view showing the finish at the top and bottom on anenlarged scale; Fig. 5 is a similar view showing a modification; Fig. 6is a small detail view of still another modification; Fig. 7 is in parta front elevation and in part a vertical section of a modified form oftank; Fig. S is a vertical transverse section through the same; Fig. 9is a horizontal section through the same; Fig. 10 is an enlarged detailyview showing the finish at the top and bottom; Fig. 11 is a fragmentarysectional View through the side of the tank; and Fig. 12 is a sectionaldetail showing a modication.

The tank may be made of any desired size and shape and will be made tosomewhat rcsemble the usual wooden tanks. Fig. 1 shows the tank inperspective with the cover omitted. The tank has the front wall 1, endwalls 2, rear wall 3, and bottom 4, all composed of sheet metal. Figs.1, 2 and 3 show the front, end and rear walls formed of a'single sheetof metal bent to form front corners 5 and rear corners 6, the frontcorners preferably being rounded, as shown, to give a neat appearance,while the rear corners may be more acute. The meeting edges of the sheet.forming the body of the tank are united by welding, the welded jointbeing indicated at 8, and running from top to bottom. The metal formingthis body is bent beyond its elastic limit so that in the finished tankthe metal is entirely in repose,

that is, it is free from internal strains. This prevents movement ortendency of movement in the metal, which would tend to crack the enamelfinish.

The bottom 4 is suitably secured to the lower edge of the body so as toform a water tight joint, preferably by welding. The top and bottomedges are provided with finishing beads so as to give a round contour toenable the enamel to adhere more readily thereto. It is well known thatenamel does not adhere well to sharp angles. The finish shown at the topedge consists of a tubular finishing strip, either like that shown at10, Fig. 4 or at 11, Fig. 5, the former giving a slightly larger bead atthe top than the lat'- ter. This tubular finishing strip is slipped downover the top edge of the body'and fasitf is more or less resilient gripsthe front end and rear walls of the 'tank' more or less firmly.Additional securing means, however, are preferably employed. As shown inthe drawings, this top strip is further secured by welding at intervals,as indicated at 12. At 13 Fig. 10 the finishing strip is shown as twohalfl rounds secured to the body.

The top and bottom beads may be a mere swell or roll formed directly inthe sheets composing the body, as shown, at 14, Fig. 6, and at 30, Fig.12, or may be a separate curved finishing strip, as shown at 15, Figs. 4and 5. This finishing strip has the curved portion 16 lying outside thetank and a comparatively flat portion 17 lying just in, side of thewalls of the tank. It is secured in place preferably by welding asindicated at 18. Fig. 4 shows the bottom 4 secured in place by weldingat 19 above the lower edge of the finishing strip 15, while Fig. 5 showssaid bottom welded at 20 below the finishing strip. Fig. 6 shows thebottom secured to the sides by a butt-weld joint 21 which is removedfrom the corner and is formed in flat portions of the sheets. Fig.

10 shows a three fourths round 22 welded.

at the lower corner.

Figs. 7 and 8 show a modification in which the front wall 1 and ends 2of the tank are formed from one sheet and the bottom 4 and rear wall 3are formed from another sheet, as indicated by the continuous corner at7 in Fig. 8. Fig. 7 also shows a cover 2S) on the tank. Thismodification, however,

is not claimed in this application but is claimed in an applicationfiled November 16, 190s, serial No. 462,855.

Fig. 9 shows a tank such as shown in Figs. 7 and 8, but reversed, thewall 3 becoming the front wall and the wall l the rear wall, with thewelds 8 at the rear vertical corners as shown and the bottom lcontinuons with the wall 3 in the saine manner as in Fig. 8.

The welding in all cases can be conveniently done by a blow-pipe system.The body is provided with an opening in its walls for receiving theflush operating device 23 and its bottom is provided with two openingsone 24, for receiving the supply connection and the other 25 for thefiushing connection. These may be reinforced by ferrules, rings orsleeves, shown at 26, that in the opening 25 also serving as a seat forthe flushing valve.

After being built up in the manner de scribed the entire tank is coveredwith a coating of enamel indicated at 27. In order to enable the enamelto adhere firmly to the sheet metal, the latter is first preferablyroughened in any suitable way, such as under an abrading wheel, thisroughening being indicated at 28, Figs. 2 and l1. The enamel is appliedin the ordinary way, that is, by heating the sheet metal tank andsprinkling onto the same the enamel powder, or by the dipping process,well understood by those skilled in this art. The enamel forms a smoothcoating over the entire surface of the tank and fills up the groovesbetween the edges of the top and bottom finishing strips and the sidesof the tank, giving a smooth finish to these points and entirelycovering up and obliterating the welds.

The tank is sightly, and exceedingly sanitary. Since the metal isstrained beyond its elastic limit, it is entirely in repose andtherefore has no tendency to move from its position of repose. Theconsequence is that the enamel firmly adheres to even the thin sheetmetal which is used.

The tank is lined on its interior with a layer of felt 31 or othersuitable insulating material. This lining acts in a two-fold capacity,one being to deaden the sounds which might be magnified by the vibrationof the thin sheet metal and the other being as a non-heat conductor toprevent the tank from sweating on the exterior on account of cold watercontained therein. This lining preferably is water-proofed, or sotreated as to withstand the action of the water.

The tank may be provided with any suitable filling and flushingmechanism.
